2019-07-19src: Make implicit fall throughs explicitJacob Garber
Implicit fall throughs are a perpetual source of bugs and Coverity Scan issues, so let's squash them once and for all. GCC can flag implicit fall throughs using the -Wimplicit-fallthrough warning, and this should ensure no more enter the code base. However, many fall throughs are intentional, and we can use the following comment style to have GCC suppress the warning. switch (x) { case 1: y += 1; /* fall through */ case 2: y += 2; /* fall through - but this time with an explanation */ default: y += 3; } This patch adds comments for all remaining intentional fall throughs, and tweaks some existing fall through comments to fit the syntax that GCC expects.

2019-07-16sb/amd/{cimx,}/sb{700,800,900}: Prevent uninitialized readsJacob Garber
There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors. -- Anonymous var_num records the number of initialized entries in the reg_var array. However, this means the index of the last initialized element is one less than the value of var_num, so we need to take that into account when indexing into the array. This has already been fixed in several other places (eg. sb/amd/pi/hudson/lpc.c), so let's also do so here.

These are defined for __SIMPLE_DEVICE__ when PCI enumeration has not happened yet. These should not really try to probe devices other than those on bus 0. It's hard to track but there maybe cases of southbridge being located on bus 2 and available for configuration, so I rather leave the code unchanged. Just move these out of arch/io.h because they cause build failures if one attempts to include <arch/pci_ops.h> before <arch/io.h>.

2017-06-13Consolidate reset API, add generic reset_prepare mechanismJulius Werner
There are many good reasons why we may want to run some sort of generic callback before we're executing a reset. Unfortunateley, that is really hard right now: code that wants to reset simply calls the hard_reset() function (or one of its ill-differentiated cousins) which is directly implemented by a myriad of different mainboards, northbridges, SoCs, etc. More recent x86 SoCs have tried to solve the problem in their own little corner of soc/intel/common, but it's really something that would benefit all of coreboot. This patch expands the concept onto all boards: hard_reset() and friends get implemented in a generic location where they can run hooks before calling the platform-specific implementation that is now called do_hard_reset(). The existing Intel reset_prepare() gets generalized as soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now easily be added later if necessary). We will also use this central point to ensure all platforms flush their cache before reset, which is generally useful for all cases where we're trying to persist information in RAM across reboots (like the new persistent CBMEM console does). Also remove cpu_reset() completely since it's not used anywhere and doesn't seem very useful compared to the others.

spi_crop_chunk is a property of the SPI controller since it depends upon the maximum transfer size that is supported by the controller. Also, it is possible to implement this within spi-generic layer by obtaining following parameters from the controller: 1. max_xfer_size: Maximum transfer size supported by the controller (Size of 0 indicates invalid size, and unlimited transfer size is indicated by UINT32_MAX.) 2. deduct_cmd_len: Whether cmd_len needs to be deducted from the max_xfer_size to determine max data size that can be transferred.

Do not map LPC ROM into the system memory space when SPI Flash is configured instead of an LPC ROM. This resolves a long-standing hard boot hang issue on the ASUS KGPE-D16 and related systems; in a nutshell, the incorrectly mapped LPC ROM overrode low memory required by ramstage, causing decompressed ramstage layout-dependent vectoring to romstage code and subsequent execution of random sections of romstage. Sometimes these random sections of romstage reconfigured the hardware in such a way that it could not access SPI Flash on the next boot attempt.

2016-12-23spi: Get rid of SPI_ATOMIC_SEQUENCINGFurquan Shaikh
SPI_ATOMIC_SEQUENCING was added to accomodate spi flash controllers with the ability to perform tx and rx of flash command and response at the same time. Instead of introducing this notion at SPI flash driver layer, clean up the interface to SPI used by flash. Flash uses a command-response kind of communication. Thus, even though SPI is duplex, flash command needs to be sent out on SPI bus and then flash response should be received on the bus. Some specialized x86 flash controllers are capable of handling command and response in a single transaction. In order to support all the varied cases: 1. Add spi_xfer_vector that takes as input a vector of SPI operations and calls back into SPI controller driver to process these operations. 2. In order to accomodate flash command-response model, use two vectors while calling into spi_xfer_vector -- one with dout set to non-NULL(command) and other with din set to non-NULL(response). 3. For specialized SPI flash controllers combine two successive vectors if the transactions look like a command-response pair. 4. Provide helper functions for common cases like supporting only 2 vectors at a time, supporting n vectors at a time, default vector operation to cycle through all SPI op vectors one by one.

2015-11-12src/southbridge/amd/sb700: Reset SATA controller in AHCI mode during startupTimothy Pearson
In AHCI mode SeaBIOS randomly fails to detect disks (AHCI timeouts), with the probability of a failure increasing with the number of disks connected to the controller. Resetting the SATA controller appears to show the true state of the underlying hardware, allowing the drive detection code to attempt link renegotiation as needed.

2015-11-12southbridge/amd/sb700: Add option to disable SATA ALPMTimothy Pearson
The AMD Register Programming Reference states that the user should have the option to disable Active Link Power Management for two reasons. First, some drives may not function correctly with the ALPM implementation of the SP5100, and second there are some situations where low latency access is more important than the power savings created by using ALPM. Allow the user to disable ALPM if desired.

2015-11-11cpu/amd: Add CC6 supportTimothy Pearson
This patch adds CC6 power save support to the AMD Family 15h support code. As CC6 is a complex power saving state that relies heavily on CPU, northbridge, and southbridge cooperation, this patch alters significant amounts of code throughout the tree simultaneously. Allowing the CPU to enter CC6 allows the second level of turbo boost to be reached, and also provides significant power savings when the system is idle due to the complete core shutdown.
